The royal family did not anticipate Kate Middleton and Prince William's love story lasting.

In 2001, they met at St Andrews University in Scotland.

The majority of those who knew them thought it was a passing fad.

After graduating from college, William worked in a variety of jobs to gain a sense of the Britain he will inherit.

Catherine was left to her own devices, but she made it.

Despite initial reservations, they have been married for over a decade and have three children.

Prince William and Kate have spent the majority of the last two decades by each other's sides.

Andrew Morton, a royal author, recently discussed the couple's love story.

The Duke and Duchess of Cambridge proved that they were born to be together.
